Hm... I still am unsure about what to do hahaha
Grab a clamp lamp (like Kiki suggested), stick a bulb in it, put a thermometer underneath. Check the temperature a few times over the next two days.
Quick and easy, especially if you already have the lamp.
You have enough days to test it and THEN order a different product if you need to. But if it works, then you're all set.
